MinGW problem with /tmp in gdomap.c

[Wim Oudshoorn]

If no one complains, I am going to commit the following
patch.

Problem
-------
On window machines that do not have a X:\tmp 
directory gdomap will not start.  
(Where X is the drive of the current working directory)

Reason
------
gdomap has the following offending line:

       if (chdir ("/tmp") < 0)

Solution
--------
Put the chdir part of code behind a 
    
    #ifndef __MINGW__ 

guard.
